The case was made out of .125 6061 plate screwed together with flat head cap screws. The front is made out of .375 6061
with an acrylic ring pressed into a hole that was bored in the
face. It is lit by electroluminescent wire behind the ring. The knob is flush with the face and supported by two bearings.
The gear set up is made from RC car gears I hade laying around.
